The authors evaluated risk factors for hyperaluminemia and aluminum toxicity in 51 CAPD patients, who received aluminum-containing phosphate binders. Serum aluminum correlated with total intake of elemental aluminum after starting CAPD (p = 0.001), with aluminum intake in the previous six months (p = 0.001), with duration of CAPD (p = 0.003), and with serum phosphate (p = 0.05). Eight patients had elevated serum aluminum, but only one had clincial evidence of aluminum toxicity (he had been on hemodialysis with untreated water until he was changed to CAPD 30 months before the study). Although the incidence of clinical aluminum toxicity appears to be low, we conclude that the aluminum intake from aluminum-containing phosphate binders is a major factor in the evolution of hyperaluminemia and, potentially, aluminum toxicity in CAPD patients. We believe that alternative effective, phosphate binders are much needed. It has been shown that tissue accumulation of aluminum in brain, bone and blood in uremic patients causes encephalopathy (I. 2), osteomalacia (3, 4), and anemia (5, 6). Clinically aluminum toxicity has been observed mainly in hemodialysis patients (1–6), although it has been reported in few cases before dialysis (7–9) and in those on continuous ambulatory peritoneal dialysis (10. II). The major cause of aluminum toxicity during hemodialysis has been transfer of aluminum from untreated water in the dialysate (1–5); this mechanism has tended to obscure the contribution of other factors, such as diet and drugs. Peritoneal dialysate contains a low concentration of aluminum (less than 15 μg/L) and there is a net removal of aluminum in the dialysate in those with serum aluminum levels within the reference range for dialysed uremics (11–13). Serial aluminum levels in CAPD patients not receiving aluminum -containing phosphate binders (ACPB) showed no significant change during a two-year follow-up (12, 14); this suggests that aluminum removal in the dialysate compensates for the failure of the kidney to excrete absorbed dietary aluminum in end-stage renal disease. Since the combination of CAPD and diet appears to have minimal influence on serum aluminum, this study was done to identify those factors which determine serum aluminum levels in CAPD patients, receiving aluminum-containing phosphate binders.

Cardiovascular mortality in the end-stage renal disease (ESRD) population remains the leading cause of death. Targeting traditional cardiovascular risk factors has proven unsuccessful in this patient population, and therefore attention has turned to risk factors related to chronic kidney disease (CKD). The toxicity of high-glucose peritoneal dialysis (PD) solutions has been well documented. The breakdown of glucose into glucose degradation products (GDP) and advanced glycation end-products (AGE) has the ability to alter cell viability and cause premature apoptosis and is strongly correlated with interstitial fibrosis and microvascular sclerosis. Biocompatible solutions have been introduced to combat the hostile milieu to which PD patients are exposed.Given the considerable cardiovascular burden for PD patients, little is known about the cardiovascular impact the new biocompatible solutions may have. This review analyzes the existing literature regarding the mechanisms through which low-GDP solutions may modulate cardiovascular risk. Interventions using low-GDP solutions have provided encouraging changes in structural cardiovascular measures such as left ventricular mass (LVM), although metabolic changes from reduced GDP and AGE exposure yield inconclusive results on vascular remodelling. It is thought that the local effects of reduced glucose exposure may improve membrane integrity and therefore fluid status. Further research in the form of a robust randomized controlled trial should be carried out to assess the true extent of the cardiovascular benefits these biocompatible solutions may hold.

Background/Aim. The disturbances of active forms of vitamin D synthesis and disturbances in calcium and posphate metabolism develop early in chronic renal failure, when creatinine clearance is about 30 ml/min. Chronic hemodialysis and peritoneal dialysis only partially correct the biochemical environment of patients on chronic renal replacement therapy because of end-stage renal disease. These dialysis modalities can?t significantly affect the endocrine disturbances of chronic renal failure and they have minimal modulatory effect. The management of disturbed calcium (Ca) and phosphate (P) metabolism and the maintainance of Ca ? P product below 4.4 mmol/l thanks to the use of dialysate solutions with the appropriate calcium concentration and the careful dosage of phosphate binders, calcium and active vitamin D metabolits, are extremely important for the prevention of renal osteodystrophy, secondary hyperparathyroidism as well as low-bone turnover disease. The aim of the study was to analyze the plasma levels of calcium, phosphate, albumin, alkaline phosphatase and parathormon (PTH) in 58 patients who were treated with continuous ambulatory peritoneal dialysis (CAPD) from March to August 2003. The use of phosphate binders and the substitution with active vitamin D metabolits were also analyzed. Methods. We examined 58 patients, 30 males and 28 female, mean-age 52 years (range, 26-78 years), affected by end-stage renal disease of the different leading cause. The average time on peritoneal dialysis program was 20 months (2-66 months). Most of the patients were treated by CAPD, while only few of them performed automatic, cyclic or intermittent peritoneal dialysis. Most of the patients used a dialysate with 1.75 mmol/l calcium concentration. Results. The study showed that our patients on chronic CAPD program during several months had normal calcemia, phosphatemia and the level of alkaline phosphatase, and that they had Ca ? P product in the recommended range. PTH serum level ranged from 16 to 490 pg/l in our patients. Conclusion. The study showed that a balanced diet and a correct dosage of phosphate binders, as well as a careful substitution with active vitamin D metabolits render a good control of calcium and phosphate serum balance, as well as an effective prevention of renal osteodystrophy development in the patients on chronic peritoneal dialysis treatment.

Of 508 patients trained for CAPD during the first five years, 115 (22.6%) were transferred to an alternative dialysis modality. Of these 87% were transferred to centre dialysis programs, equally divided between hemodialysis and intermittent peritoneal dialysis. Advanced age favoured transfer to intermittent peritoneal dialysis and failure due to peritonitis, transfer to hemodialysis. Three year survival after transfer from CAPD was 38%. The presence of diabetes and advanced age adversely affected survival after transfer. Dialysis modality and peritonitis as the cause of CAPD failure did not affect survival. Other treatment options are available to patients who fail CAPD. A relatively high drop-out is therefore acceptable and preferable to continuing CAPD in patients encountering complications which might ultimately influence their survival. Since its introduction in Toronto in 1977, continuous ambulatory peritoneal dialysis (CAPD) has achieved increasing prominence in the management of end-stage renal disease. Throughout its comparatively short history, one of the major criticisms of this technique has been the relatively high drop-out rate. This report provides a follow-up of patients transferred from CAPD to alternative dialysis modalities.

This paper has reviewed experience in Belgium with 99 patients on CAPD. They represent 6-7% of all dialysis patients in this country. The principle reasons for selecting CAPD were old age, problems with vascular access and major cardiovas cular complications. Hemoglobin and hematrocrit values increased in all patients but preliminary measurements of red cell volume in some of them showed no change. Most patients showed moderate increases in serum triglycerides. In three non-diabetic patients with marked elevation in triglyceride levels, insulin, given intraperitoneally, prevented further increases. The frequency of peritonitis was still high; the average rate was one episode every 7.6 patient months. Other major complications included hypotension, which improved after the substitution of dialysate with a higher sodium concentration, severe respiratory disease and gangrene of the legs. After a mean follow-up of seven months, the death rate was 18% and the rate of technical success was 70%. The fact that most of our patients were in the high-risk category should be kept in mind when comparing these results with those obtained with other modes of treatment. At the end of 1978, a total of 1195 patients with end-stage renal disease (ESRD) were treated on either home or hospital dialysis in Belgium. There were 50 dialysis centers for a total population of 9.8 million. Of these 1195 patients, only seven were treated with either continuous ambulatory peritoneal dialysis (2-4) or intermittent peritoneal dialysis. Since then and until July 1, 1980 the number of patients treated with CAPD in Belgium has increased to 99 and this paper describes our experience with these patients.

Background This report describes the status of renal replacement therapy (RRT), particularly continuous ambulatory peritoneal dialysis (CAPD), in Romania (a country with previously limited facilities), outlines the fast development rate of CAPD, and presents national changes in a European context. Methods Trends in the development of RRT were analyzed in 2003 on a national basis using annual center questionnaires from 1995 to 2003. Survival data and prognostic risk factors were calculated retrospectively from a representative sample of 2284 patients starting RRT between 1 January 1995 and 31 December 2001 (44% of the total RRT population investigated). Results The annual rate of increase in the number of RRT patients (11%) was supported mainly by an exponential development of the CAPD population (+600%); the hemodialysis (HD) growth rate was stable (+33%) and renal transplantation had a marginal contribution. The characteristics of both HD and PD incident patients changed according to current European epidemiology (increasing age and prevalence of diabetes and nephroangiosclerosis). There were significant differences between PD and HD incident populations, PD patients being significantly older and having a higher prevalence of diabetic nephropathy and baseline comorbidities, probably reflecting different inclusion policies. The estimated overall survival of RRT patients in Romania was 90.6% at 1 year [confidence interval (CI) 89.4 – 91.8] and 62.2% at 5 years (CI 59.4 – 65.0). The initial treatment modality did not significantly influence patients’ survival. There was no difference in unadjusted technique survival during the first 2 years; afterwards, there was a clear advantage for HD, with more patients being transferred from PD to HD. Several factors seemed to significantly and negatively influence PD patients’ survival (Cox regression analysis): male gender, lack of predialysis erythropoietin treatment, and initial comorbidities. Stratified analysis to discover the influence of these factors on patients’ survival revealed that HD was associated with an increased risk of death in the younger nondiabetic end-stage renal disease population, regardless of other coexisting comorbid conditions. However, in older patients (>65 years) and in diabetics, regardless of the presence or absence of associated comorbid conditions, there was no significant difference in death rates between HD and PD patients. Conclusions We report an impressive quantitative and qualitative development of CAPD in one of the rapidly growing Central and Eastern Europe countries. CAPD should be the method of choice for young nondiabetic end-stage renal disease patients. Improvement in predialysis nephrologic care and in transplantation rates is required to further ensure the ultimate success of the Romanian PD program.

Background: This study analysed children with end-stage renal disease treated with automated peritoneal dialysis (APD) in our centre to explore the risk factors associated with residual renal function (RRF) loss. Methods: Children treated with APD as the initial renal replacement therapy regimen from January 2008 to December 2016 were included. All the children had a daily urine volume of ≥100 ml/m2 when APD was initiated and a dialysis follow-up time of ≥12 months. A daily urine volume of <100 ml/m2 after 12 months of APD treatment was defined as loss of RRF. Possible risk factors that may be associated with RRF loss were analysed. Results: A total of 66 children were included in the study. After 12 months of APD treatment, the daily urine volume decreased by 377.45 ± 348.80 ml/m2, the residual glomerular filtration rate decreased by 6.39 ± 3.69 ml/min/1.73 m2 and 29 of the patients (43.9%) developed RRF loss. The higher risk of RRF loss after 1 year of APD treatment was most pronounced in patients with daily urine volume of ≤400 ml/m2 before treatment, higher glucose exposure and higher ultrafiltration volume, while the lower risk of RRF loss was in patients with administration of diuretics. Each increase of 1 g/m2/day glucose exposure was associated with a 5% increase in RRF loss (odds ratio (OR) 1.05, p = 0.023) and each increase of 1 ml/m2/day ultrafiltration volume was associated with a 1% increase in RRF loss (OR 1.01, p = 0.013). Conclusion: In children undergoing APD, the risk for loss of RRF is associated with low urine volume at the start of APD, high glucose loading and high peritoneal ultrafiltration volume, while preservation of RRF is associated with the usage of diuretics.

Background Peritoneal dialysis (PD) has become an increasingly important treatment modality for end-stage renal disease. However, application of PD in patients with liver cirrhosis (LC) and subsequent outcomes have not been thoroughly evaluated. Methods A total of 1,366 patients (≥ 18 years old) who started PD at 4 tertiary referral centers between January 2000 and December 2015 were initially reviewed. Among them, 45 patients with LC were finally analyzed (LC-PD). Using the multivariate Cox hazard ratio (HR) model, outcomes such as technique failure, infection, and mortality in patients with LC-PD were compared with those in non-LC-PD patients (non-LC-PD) or patients with LC who received hemodialysis (LC-HD). All of the patients were selected by 1:1 matching of age, sex, catheter insertion date, and diabetes mellitus. Results During the mean follow-up duration of 43 ± 35.8 months, 12 patients with LC-PD experienced technique failure, and this rate was similar to that of non-LC-PD patients. In evaluating infection episodes, the most common causes for peritonitis and exit-site infection were Escherichia coli (5.8%) and Staphylococcus aureus (19.3%), respectively; these event rates of LC-PD did not differ from those of non-LC-PD. The all-cause mortality rate of the LC-PD group was not different from that of the non-LC-PD and LC-HD groups. Conclusion Dialysis outcomes such as technique failure, infection, and mortality are not affected by the presence of LC. Accordingly, PD therapy is a good option in patients with LC.
